The Abyss
Scored from 440 calibrated IMDb reviewers, each re-centered on their own rating baseline before the title is ranked. Cohort: Films · 1980s (3,141 peers).
Summary
A civilian deep-sea oil drilling crew is recruited by the Navy to search for a lost nuclear submarine on the edge of an undersea trench. As they descend, the team's estranged foreman and his engineer ex-wife clash with an unstable SEAL officer while encountering something not of this world in the depths below.
Released in 1989, The Abyss is an adventure, drama and mystery film.
A second review pool sits behind it as well: 28 Rotten Tomatoes reviewers clear the same calibration test, and Rankquant scores them separately. 3,140 other films from the 1980s form the cohort it is ranked inside. 440 IMDb reviewers rate with enough spread for a personal baseline to be measured, and those are the ones the calibrated score reads; a separate, broader pool of 450 reviewers with at least two reviews each feeds the raw-average track.
How the score was built
We compare the reviewers of this title against every other title those same people reviewed. Each review is scored relative to the reviewer's own baseline — a 7/10 from a hard grader sits well above their average, while a 7/10 from a generous grader sits below theirs. Every reviewer then counts the same, so the result is a calibrated consensus rather than a raw average.
- Global percentile
- Where The Abyss lands against every title we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — titles of the same format released in the same decade. A 1970s film is judged against 1970s films, not against last year's streaming series. Ranked against Films · 1980s (3,141 titles).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each title keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 440.
